Anti-nutritional properties and organic acids composition of seven varieties cassava (Manihot esculenta Crantz) consumed in Côte d’Ivoire

Abstract

In Cote d'Ivoire, new varieties cassava (Manihot esculenta Crantz) are produced and consumed by populations. The aim of this research work was to study the anti-nutritional and antioxidant properties, organic acids of seven varieties cassava (Agbable 3, Bondoukou 4, Bonoua 2, Boufouh 3, Boufouh 4, Soclopouopo 3 and Totoba 2) to better value them. Thus, phytate contents varied from 50.34±0.03 (Bondoukou 4) to 60.36±0.04 mg/100g (Soclopouopo 3), those of tannins contents from 0.046±0.014 (Agbable 3) to 0.054 ± 0.014 (Bondoukou 4). The flavonoid contents range from 0.62 ± 0.02 (Agbable 3) to 3.01 ± 0.01 mg / 100 g (Bonfouh 3). Total polyphenols ranged from 51.24±1.79 (Totoba 2) to 81.12±1.97 mg/100 g (Bondoukou 4). Oxalates contents varied from 5.1±1 (Agbable 3) to 5.6±1.5 (Bondoukou 4). Anti-oxidant power varied from 0.06 (Agbable 3, Bondoukou 4, Bonfouh 3) to 0.08 (Boufouh 4). Most abundant organic acids are carboxylic acids ranging from 122.5±2.04 (Boufouh 3) to 147.65±0.61 μg/100g (Bonoua 2) and benzoic acids from 80.11±0.17 (Boufouh 3) at 126.15±0.98 (Bondoukou 4). Agbable 3 variety has low contents of tannins, flavonoids, total phenolols and oxidizing power. Bondoukou 4 and Bonoua 2 varieties respectively had low contents of phytates and total polyphenols.
